I have a question about food allergies.?

My 5 yr old daughter is allergic to dairy, eggs, peanuts and treenuts. I was wondering if anyone out there has taken their child to Disneyland and if you had luck with the chefs making safe meals for your kids. I would like to take her to Ariel's Grotto and wonder if anyone has had experiences with them there. I would really like to take her there, but it wouldn't be worth it if she became ill.
